With the deadly asteroid Thanatos bearing down on planet Earth, an elite fighting force known as the Dragonauts flies into action. These space junkies can really fill out a uniform, and their courageous Dragon comrades are fearless and foxy in the face of danger. Following the lead of interplanetary lovebirds Jin and Toa, humans and dragons team up for a romp in the lunar hot springs and a showdown with the nefarious Gillard Army. The fate of humanity rests on Jin and Toa, who must harness the power of their cosmic hook-up in order to stop Thanatos and build a new life for a lonely boy and the dragon of his dreams.
